Abstract

A coin hopper for use on vending machines utilizes a transparent housing having openings at the top and bottom thereof for the passage of coins or liquids. A first downwardly slanted support surface is provided whereby coins or liquids entering the opening at the top of the hopper gravitate downwardly free falling at the end of the first support surface onto a second downwardly slanted countersunk perforated support surface. Liquid falling onto the second downwardly slanted perforated support surface passes through the countersunk perforations into a compartment located therebelow. Coins, on the other hand, gravitate downwardly along both downwardly slanted support surfaces free falling at the end thereof into a coin changer. A tube connected to an aperture in the bottom of the compartment drains liquid collected within said compartment. Use of the downwardly slanted countersunk support surface having a compartment therebelow prevents liquids which may enter the hopper from flowing downwardly into the coin changer causing malfunction thereof or causing dangerous electrical conditions to occur.

DESCRIPTION OF THE PREFERRED EMBODIMENT OF THE INVENTION

Referring to FIGS. 1 and 3 of the drawings, the liquid diverting coin hopper 1 comprises a housing 2 having

side walls

4 and 6, a front wall 8 which has an extension section 9, and

flanges

10 and 12 integrally formed on a single sheet of rigid clear plastic material.

The

side walls

4 and 6 have rearwardly downwardly extending slanted top edges 14 and 16 which support a top wall 18 having a front edge 22.

Sides

4 and 6 have downwardly extending

front side edges

24 and 26 which terminate at juncture edge 27. The front wall 8 slants downwardly and inwardly and terminates in a bottom edge 30. The extension 9 of the front wall 8 is turned inwardly at edge 27 between the

side walls

4 and 6 forming a rounded lip 31. The

side edges

33 and 35 of the extension section 9 are secured to the

insides

37 and 39 of the

side walls

4 and 6 such that the extension section 9 forms a first downwardly extending, slanted support surface 40 for the gravitational support of a coin 41 or liquid 43 which may enter chute 45 from coin slot 47 located in the front panel 49 of a vending machine.

The

side walls

4 and 6 have horizontal bottom edges 51 (one shown) which lie in the same plain as the bottom edge 30 of wall 8. The bottom horizontal edges 51 terminate at juncture 50 and then continue downwardly forming bottom

slanted edges

53 and 57, FIG. 2, to which is attached a bottom wall 59 having upper edge 65 and lower edge 67 the latter having an extension lip 68 thereon. The

side walls

4 and 6 have rear bottom edges 69 (one shown) extending downwardly below the ends 73 and 75 of the

flanges

10 and 12. A rear wall 77, FIG. 1, having a bottom edge 79 is secured to the

flanges

10 and 12 and to the bottom edges 69 by suitable means with the bottom edge 79 resting on the extension lip 68 of the bottom wall 59. Said

flanges

10 and 12 and said rear wall 77 secured to a panel 78 within the vending maching.

Thus constructed, the

side walls

4 and 6, bottom wall 59 and rear wall 77 define a compartment 60 for collecting liquid 43 which may enter the hopper through coin slot 47.

A second support surface 80, FIG. 1, slants downwardly and oppositely to that of the first slated surface 40, has an end 81 secured to rear wall 77 and an end 83 secured to the upper edge 65 of bottom wall 59. The sides of support surface 80 are secured to the inside of

side walls

4 and 6. The second downwardly slanted surface 80 has a plurality of apertures 84 therein which will permit liquid 43 entering the coin hopper top opening 46 to pass therebetween thus falling into the compartment 60 therebelow. The apertures 84 having some of their peripheries substantially touching and are countersunk at 86, FIG. 4, and act to draw the liquid 43 in a syphen-like fashion into the compartment therebelow. Notches 82 are cut in the sides of support surface 80 and intersect the aperatures 84. Liquid is thus prevented from flowing down along the sides of this support surface into the coin changer therebelow. Bottom edge 30, horizontal edges 51 and end 83 of the perforated slanted surface 80 which is attached to upper edge 65 of bottom wall 59 define an opening 48 in the bottom of the hopper through which a coin passes falling over the end 83 into a coin chute 115 descending into a coin changer 117.

An aperture 95, FIGS. 1-2, is provided in one of the side walls of the hopper at the bottom section 97 thereof, has one end 98 of a flexible tube 99 tightly secured therein by suitable means. The opposite end 100 of the flexible tube 99 is secured to the vending machine such that liquid 43 collected within compartment 60 will drain to the outside thereof.

A plate 103, FIG. 2, has an upwardly projecting surface 105 having a bevelled lip 107. The bevelled lip 107 lies adjacent to and overhangs the rounded lip 31 of front wall 8. The plate 103 is secured to the inside wall 111 of front panel 49 of a vending machine by any suitable means. The bevelled lip 107 overhangs the rounded lip 31 such that liquid 43 which may enter coin slot 47 in a trickle-like fashion will descend along chute 45 dripping over edge 50 onto the lip 107 and subsequently flow downwardly along surface 105 where it will travel travel downwardly between the plate 103 and the inside wall 111 of the front panel 49 of a vending machine away from the entrance 115 of the coin changer 117.

In operation, when a coin 41 having a diameter greater than the diameter of the apertures 84 of the second downwardly slanted support surface enters the slot 49 it will slide downwardly along the chute 45 and enter the opening 46 of the coin hopper housing 2. The coin will travel downwardly along the slanted surface 40 dropping over the semi-circular end 91 of said surface free falling downwardly through opening 90 onto the downwardly slanted perforated surface 86 descending downwardly therealong until it drops through opening 48 at the bottom of the hopper falling into the chute 115 of coin changer 117.

In the event that liquid 43 may enter the coin slot 47 under pressure, the liquid will travel downwardly over the first slanted surface 40 falling through the opening 90 and onto the perforated downwardly slanted surface 80 whereby it will pass through the countersunk perforations 84 falling into the compartment 60 therebelow. The liquid will be drained away through the aperture 95 and the flexible tube 98. Should the liquid not have sufficient force or pressure to enter the upper housing opening 46, it will be caught by the lip 107 and flow downwardly along surface 105 draining between the plate 103 and the inside wall 111 of the vending machine front panel 49 away from the entrance 115 of the coin changer 117.

Thus constructed, the liquid which may enter the coin hopper is diverted from falling through the opening 48 at the bottom of the hopper housing 2. By using countersunk perforations in surface 80 and compartment therebelow, the liquid is prevented from entering into the coin changer located below the hopper thus avoiding dangerous electrical conditions from occurring within the coin changer which could result in possible personal injury, destruction and malfunction of both the vending machine and coin changer.

Liquid forced into the vending machine through the coin slot and entering the coin changer thereof has, in the past, created malfunction of the coin changer, caused serious hazardous conditions to prevail resulting in destruction of the vending machine. With the installation of this liquid diverting coin hopper to existing vending machines, liquid is prevented from entering the coin changer thus preventing the above enumerated hazardous conditions and malfunctions from occurring.

While the invention has been shown and described with respect to a preferred embodiment thereof, it will be understood by those skilled in the art to which this invention pertains that the foregoing description may be changed in form and detail without departing from the spirit and scope of the invention.
